I agree that apologizing withing normal boundaries is a good idea. If I were feeling"normal" and hurt someone's feelings or did the wrong thing I would apologize. So I sort of use that as a measuring stick. But no I would not be saying I am sorry all the time. With my close friends and family, I try to let them know that I will be manic and may say the wrong thing. I encourage them to help let me know if I am doing this or acting inappropriately. Then I know I need a med adjustment.
